Definitions

  • a method of handling interworking from 5G system (5GS) to 2/3G for an MA PDU session with a 3GPP EPS PDN leg is proposed.
  • a UE maintains an MA PDU session in 5GS, which has one leg and one path to the data network.
  • a PDN connection in EPS is established as a user plane resource on 3GPP access (the 3GPP PDN leg).
  • the UE performs intersystem change to A/Gb or Iu mode, e.g., due to poor radio signal coverage in EPS.
